Linear OOA(9¹²¹, 79, F₉, 2, 69) (dual of [(79, 2), 37, 70]-NRT-code), using OOA 2-folding based on linear OA(9¹²¹, 158, F₉, 69) (dual of [158, 37, 70]-code), using

discarding factors / shortening the dual code based on linear OA(9¹²¹, 159, F₉, 69) (dual of [159, 38, 70]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81³⁴, 53, F₈₁, 34) (dual of [53, 19, 35]-code or 53-arc in PG(33,81)), using
    - discarding factors / shortening the dual code based on linear OA(81³⁴, 81, F₈₁, 34) (dual of [81, 47, 35]-code or 81-arc in PG(33,81)), using
      - Reedâ€“Solomon code RS(47,81) [i]
  2. linear OA(9¹, 3, F₉, 1) (dual of [3, 2, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(9¹, s, F₉, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
